U.S. Sen. Lindsey Graham, R-S.C., Sunday rejected a House Intelligence Committee investigation of the attack on the U.S. Consulate in Benghazi, Libya, that left four Americans dead. He called it “full of c---” during an appearance on CNN’s “State of the Union.”

“I don’t believe that the report is accurate, given the role that Mike Morell [deputy director of the CIA at the time] played in misleading the Congress on two different occasions. Why didn’t the report say that?” Graham asked. He then added, “I think the report is full of c---.”

The Republican-led House Intelligence Committee Friday released its findings, which concluded the administration did not intentionally mislead the American public about the Sept. 11, 2012, attack on the consulate in Benghazi that killed U.S. Ambassador to Libya J. Christopher Stevens and three others.

“The bipartisan panel concluded that there was no stand-down order issued by or to intelligence community personnel, and there was no denial of air support to intelligence community officers on the ground,” committee Chairman Mike Rogers, R-Mich., said in a statement. “The committee did receive evidence about the activities of the Defense Department, State Department and White House personnel, which are explained in both the report and the additional views.”

Graham said it’s “a bunch of garbage” that no member of the Obama administration was found to have lied about what happened and said the committee did “a lousy job” of investigating.

“When Susan Rice was on television after the attack, she said on three different occasions the consulate was strongly, and significantly secure,” Graham said. “Nothing could be further than that from the truth, and there’s nothing in the talking points about the level of security.”
